What are your requirements? If you want to increase the output level of your CD player, you might build a SRPP stage.
If you don't need more output level, a simple Cathode Follower stage would be a good choice.
The benefit of these two types of amplifier stages is their low output impedance, making the choice of audio cables less critical.
